STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 677,779, dated July 2, 1901.

Application filed April 3, 1901.

To all whom it may concern:

Be it known that 1, CHARLES, A. Krrrs, of Oswego, in the county of Oswego, in the State of New York, have invented new and-useful Improvements in Steam-Boilers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and ex tively, whereby the flue openings or perfora tions in said dry plate or diaphragm may'be readily alined with similar apertures or fineopenings in the opposite heads of the boiler, so that the fines may be readily inserted through said openings without the necessity of bending said fines to conform to any variation in the alinement of the apertures of the diaphragm with those of the heads.

, To this end the invention consists in the combination and arrangement of the parts of a steam-generator, as hereinafter fully described, and pointed out inthe claims.

Referring to the drawings, Figure 1 isa transverse vertical sectional view through my improved steam-generator, showing 'the water-inlet and steam-outlet conduits as con nected, respectively, to the lower and upper heads of the boiler-shell. Fig. 2 is a'transverse sectional View through the detached diaphragm or dry plate, showing the adjacent ends of the arms which support said diaphragm in position. Fig. 3 is an isometric view of the detached diaphragm or dry plate, showing the relative position ofthe supporting legs or arms secured thereto.

Similar reference characters indicate corre= 7 sponding parts in all the views.

As shown in the drawings, this invention consists of a boiler-shell1, composed of upper and lower sections 2 and 2, having their adjacentends open and provided with annular flanges engaged with each other and secured together by suitable fastening means, as rivets or bolts at. These sections are preferably formed of substantially the same size,

vention. 1

The heads 3 and e are each provided with a series of flue openings or'apertures4, which are alined with each other and are arranged to receive the opposite ends of a series of upright fines 5, which ends after being inserted into the heads are then expanded or upset for securing the same in position. The upper head is provided with asteam-outlet passage or conduit 6, and the lower head with a suit= able Water-inlet conduit 6', which, however, may be otherwisearranged than as indicated in the drawings. v

Arranged Within the boiler or shell 1 is a diaphragm or dry plate '7, which is loosely supportedin a planesubstantially parallel with the heads 3 and 3, being of substantially the same diameter and general contour as the inner diameter of the shell 1 and p is preferably arranged in closer proximity to the upper head 3 than to the lower head 3' for dividing the interior of the shell 1 into a .lower water-containing compartment and an upper steam-compartment. The primary object of this plate 7 is to prevent the foaming or undue splashing of the water within the boiler-shell, and although it may be supported in any desired manner, so as to permit its free rotary movement within the boiler-shell and independently thereof, I preferably provide the dry plate or diaphragm with one or more arms 8 and 9, projecting, respectively, from its upper and lower faces, the lower end faces of the depending arms 9 being arranged to rest upon the upper face of the lower head 3" for supporting the diaphragm, and the upper ends of the arms 8 being arranged to engage the lower face of theupper head 3 for additionally supporting the diaphragm in position during the insertion of the tubes 5, it being understood that said diaphragm is provided with a series of apertures 10, corresponding to the number of apertures in one of the heads 3 or 3 or, in other words, corresponding to the number of fines employed in the boiler.

It is well known that in b'oilers of this characterin which the diaphragm is secured firmly in positionitis very difficult to aline the apertures of said diaphragm with the flue-openings in the' heads and that therefore when the lines are inserted in position it is neces- 'sary to bend the lines in order to conform to the variations in the alinement of the apertures in the diaphragm with those of the heads. By loosely mounting the diaphragm within the boiler, as'shown, described, and claimed as my invention, it is evident that when the fines are .inserted the diaphragm may be readily rotated a slight. distance, thereby alinin'g the apertures of the dry plate with the similar apertures of the heads and permitting the fines tobe not only readily inserted, but also obviates the necessity for bending said fines, and thereby destroying their utility and effectiveness. This is aparticularly important feature of my invention, and while reducing the expense in assembling the partsof the boiler it also increases the strength of theboiler and permits the diaphragm to readily adjust itself for the purpose of alining the apertn res therein with the aperturespfthe head. Although this dia phragm is formed of substantially the same diameter as the inner diameter of the drum, yet it is apparent that the flue-openings may bemade a little larger than the flues,and the diameter of said diaphragm may be slightly less than the interior diameter of the'shell for permitting the passage of the steam from thewaterchamber to the steam compartment; but in order to further provide for this passage of the steam the diaphragm. is

'formedwith a series of small steam-passages 11,-as shown particularly in Fig. 3. I

l The operationof my invention will now be readily understood upon reference to the fore- 1 going description and the accompanying drawings, and it will be noted that the diaphragm may be otherwise supported than as seen in the drawings-as, for instance, the periphery of said diaphragm may be inter posed between flanges projecting from the inner face of the shell in such manner as to permit the diaphragm to rotate, or, rather, ad-

just itself so as to aline its apertures with the similar apertures of the heads.

Having thus fully described my invention, what I claim as new, and desire to'secnre by Letters Patent, is-' I 1. A steam-boiler comprising a shell having opposite perforated heads and fire-fines within the shell and having their opposite ends inserted in the apertures of the heads, and a transverse plate between the heads and provided with perforations receiving the flues, said plate being slightly rotatable for permitting the alinement of its apertures with those of the boiler-heads, when the lines are being inserted in position, and means for preventing endwise movement of the plate.

2. The combination with a steam-boiler composed of opposite hollow sections formed of substantially the same size and having adjacent ends open and secured to each other and their outer ends provided with perforated'heads, an intermediate transversepershell having opposite perforated heads, a circular plate loosely supported transversely within the shell and f formed of substantially the same diameteras the interior of the shell,

said platebeing formed'with apertures corresponding to the perforations in the heads and provided with steam-passages therethrough, and fines passed through the apertures and perforations of said platefand heads andhaving theirends secured to the heads.

4. Ina steam-boiler the combination of oppositely-arranged hollow sections having their adjacent ends open and secured to each other and their opposite ends provided with heads having flue-openings, a plate loosely supported within the shell between the meeting ends of the sections and one of said heads and arranged substantially parallel with the heads,

said plate being provided with flue-openings and steam-passages thereth'rough, and fines inserted through said openings of the heads and plate and secured to the heads, and means for preventing endwise movement of the plate. r

5. In a steam-boiler the combination of 0ppositely-arranged hollow sectionshaving their adjacent ends open and secured to each other and their opposite ends provided with heads having fine-openings, a plate loosely supported in the shell between the meeting ends of the sections and one of said heads and arranged substantially parallel with the heads,

said plate being provided with flue-openings and steam-passages therethrough, and flues inserted through said openings of the heads and plateand secured to the heads and bars or rods secured to the plate and projecting in opposite directions therefrom for engaging the opposite heads and preventing endwise movement of the plate.

6. The combination with an upright tubular boiler of a transverse plate loosely mounted in the boiler between itsopposite heads and parallel therewith, said plate being pro vided with openings receiving the fines and with oppositely-projectingarms engaged with the heads for holding the plate from endwise movement.

In witness whereof I have hereunto set my hand. I
